Uber reportedly paid a 20-year-old Florida man $100,000 via a bug reporting reward system to keep the data breach of 57 million users information a secret.

Reuters reports that a 20-year-old man from Florida was behind the data breach last year that saw the information of 57 million Uber users and drivers exposed.

Uber covered up the hack for over a year, only revealing the data breach in November, and paid the man to delete the stolen data using a “bug bounty” system, usually used to pay coders that spot code vulnerabilities.

Uber reportedly used their bug bounty service, hosted by a company called HackerOne, to transfer the payment to the man.

A payment of that size through a bug bounty system would be highly irregular, and one former HackerOne executive said that such a payment would be an “all-time record.”
